Yesterday an official ICS (Ice Cream Sandwich, Android 4.0) build for AT&T’s Galaxy S2, (non-LTE) was leaked to the public. The build was quickly ready for an Odin flash thanks to the people at RootzWiki. I was able to download and install Samsung Kies (for the Windows drivers) in moments. Then I downloaded Odin from RootzWiki and began pushing it out to my GS2. I have to say the process, as always, was pretty straight forward. I’ll run through the process and possible issues in a moment. Once completed the process I had my GS2 running the sweet ICS we’ve all looked forward too! The OS does have TouchWiz running on top; however it is so clean that as in previous version it blends very well. I did run a few speed tests following my flash to ICS and was averaging around 7000kbps down and 1000kbps up. Prior to the upgrade I had averaged around 3500kbps down. I think that shows a dramatic increase in speeds. So far the only issue I have found is with the alarm clock and the ability to schedule it for different days. I’m assuming this will be fixed before the its officially released. I was able to fix it by just installing a separate alarm clock app. I don’t have very much more input yet as I haven’t messed with it much more. I look forward to playing with it a lot more and playing with all the awesome features that the latest Android version has to offer. – Greg
